To all whom t may concern.'

Be it known that I, ORIN C. FENLAsoN, a citizen of the United States, residing at Hoquiam, in the county of Chehalis and State of Washington, have invented a new and useful Anvil for Stapling-Machines, of which the following is a specification.

The invention relates to improvements 1n anvils for stapling machines.

The object of the present invention is to improve the construction of stapling machines, more especially the construction of the anvil, and to provide a stapling machine designed for stapling veneer in the construction of collapsible boxes, and equipped with an anvil and a plurality of staple forming and driving mechanisms, adapted at each operation to drive the staples simultaneously into the overlapped ends of a strip of veneer at spaced points in one of the walls of the box in close proximity to the adjacent corners without removing the veneer from the stapling machine.

The invention also has for its object to provide a machine of this character, capable also of permitting the stapled veneer strip, which forms the body of the box, to be placed on the anvil laterally of the same for stapling a separate strip of veneer to one of the walls of the box for forming the bottom thereof and for analogous purposes.

iVith these and other objects in view, the invention consists in the construct-ion and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacricing any of the advantages of the invention.

In the drawings z-Figure 1 is a perspective view of a stapling machine, constructed in accordance with this invention. Fig. 2 is a front elevation of the anvil, showing a strip of veneer with overlapped ends arranged on the anvil to form the body of a box. Fig. 3 is a side elevation of the anvil, the box being arranged in a lateral position on the same for securing a separate strip to the body of the box. Fig. 4 is a plan view of the anvil. Fig. 5 is a transverse sectional view of the same on the line 5 5 of Fig. 4. Fig. 6 is a perspective view of the anvil. Fig. 7 is a similar view of one of the gages.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

In the accompanying drawings in which is illustrated the preferred embodiment of the invention, the wire stapling machine is designed for stapling collapsible veneer boxes, similar to those forming the subjectmatter of a companion application, executed by me of even date herewith. The wire stapling machine is equipped with two spaced staple forming and driving mechanisms 1-1, located above a lateral extension or projecting portion 2 of an anvil 3. The anvil 3, which projects forwardly or outwardly from a standard 4, or other suitable support, is located beneath the staple forming and driving mechanisms in line with the same, and it is provided at its inner end with an integral tubular portion 5, tted on the standard 4 and suitably secured to the same and provided at opposite sides with horizontally projecting anges 6, which form supports for gages 7 and 8. The particular construction of the staple forming and driving mechanisms, which simultaneously form and drive the staples, does not constitute a portion of the present invention, and a detail description of the construction and operation of this mechanism is, therefore, deemed unnecessary, as any desired construction of staple forming and driving mechanisms may be employed in connection with the improved anvil.

The lateral extension 2, which is formed integral with the anvil, as clearly illustrated in Fig. 5 of the drawings, projects from one side of the anvil, which is providedat the opposite side with a beveled or inclined face 9, extending upwardly and inwardly from the vertical side face 10 of the anvil to the upper face of the extension 2, which is arranged at the top of the anvil and which constitutes the upper working face of the same. The lateral extension 2 is of a length less than the body portion of the anvil 3, and it is provided in its upper face with sockets 11 for the reception of clench blocks,

12, coperating with the staple forming and driving mechanisms and detachably secured in the sockets by clamping screws 13. f

The projection of the anvil from the support or standard 4 of the machine enables a strip 14 of veneer to be placed on the anvil with its ends 15 overlapped to form the body of the box, as clearly illustrated in Fig. 2 of the drawings. The veneer vstrip is transversely scored at four points to form a rectangular box, and the overlapped ends are coincident with one of the walls of the box and constitute a double wall of two thicknesses, which are adapted to receive between them the flap at the free end of a separate bottom strip 16, vwhen the box is set up for use. As illustrated in Fig. 3 of the drawings, t-he strip 16, which forms the bottom of the box, is stapled at one end to the wall diametrically opposite the double wall or wall of two thicknesses, and in setting up the box, the free end of the strip 16, which is scored to form a iia p,`is inserted between thetwo thicknesses of the double wall. The beveled face 9 of the anvil enables the body of thebox to be placed in rhomboidal form on or around the anvil in order to bring the clench blocks and the staple forming and driving mechanisms suf'- ficiently close to the corner of the box. After stapling the overlapped ends in the position shown in Fig. 2 of the drawings, the box is shifted to the right to arrange the opposite portions of the overlapped ends over the anvil in position to receive a set of staples. This shifting of the box may be effected without removing the same from the anvil.

After stapling the overlapped ends of the strip of veneer to form the body of the box, the latter is withdrawn from its position surrounding the anvil, and it is placed at the .side of the anvil having the lateral extension, which extension projects into the body of the box, the separate bottom forming strip having been previously placed in position ragainst the inner face of the wall or side of the body of the box to which it is to be secured. While in this position the separate strip extends in a direction laterally of the anvil and is out of the way of the operator. The stapling machine is then operated to simultaneously drive the staples through one of the walls of the body and the separate strip, which forms the bottom of the box. The stapling machine may be used for a variety of other purposes, as the anvil forms a double anvil and enables a box or similar body to be arranged in different positions at right angles Vto each other, and to have a plurality of staples driven into it at each operation of the machine.

The gages 7 and 8, which may be constructed of sheet'metal, or other suitable material, are arranged in vertical planes and are provided with horizontal attaching portions 17 and 18, extending rearwardly from the vertical body portion of the gages and provided with slots 19 and 20, through which pass screws 21 and 22, mounted upon the horizontal flanges 6 of the tubular portion of the anvil for securing the gages in adjustment. The independent adjustment of the gages enables them to be arranged to properly position the material when the same is arranged in either of the said positions on the anvil. The gages 7 and 8 are located at opposite sides of the inner portion Y of the anvil contiguous to the flat side faces of the same, as clearly shown in Fig. 4l of the drawings. While the wire stapling machine with the staple forming and driving mechanisms is illustrated in the drawings in an upright position, yet it will be readily understood that those parts will operate in a horizontal, inclined, inverted, or any other position. 1

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a wire stapling machine, the combination with a plurality of staple forming and driving mechanisms, of an anvil located in line with the said mechanisms and consisting of a projecting arm or portion provided with a lateral extension against ywhich the staples are clenched, said extension being arranged to project into a box or similar article when the samevis placed against the side of the anvil, whereby such box or article may be arranged on the anvil in different positions at right angles to each other to receive a plurality of staples from the said mechanisms at each operation of the machine.
